Fixed errors in I/O handling of cfeditor.CMapFileDecode.
Moved encoding declaration from CMainControl to CFileReader.
Changed cfeditor.CMapFileDecode.decodeMapFile to throw IOException and FileNotFoundException instead of GridderException.
Fixed documentation of daieditor.CMapFileDecode.
Moved CFileInputStream and CFileReader to Gridarta.
Improved cfeditor MultiPositionData I/O code.
Changed storage location of Daieditor's python menu definition.
Unified script editor and moved it to Gridarta.
Improved CFileInputStream's file lookup. It now should create paths correctly and thus find files in the jar again.
cfpython_menu.def is now included in Gridarta and stored in all three jars (crossfire editor, daimonin editor and yet unused common gridarta jar).

Sorry for the large changeset, I did these changes during a LAN party that had no Internet Access.
